HEAD-LIGHT.

SPECIFICATION forming part of Letters Patent No. 364,401, dated June. '7, 1887.

Application filed July 10, i583. Renewed April 30, 1985. Again renewed March 18, 1887. Serial No. 231,470. (No model.)

To all whom, it may concern.-

Be it known that I, W'ILLIAM DUTCH, of the city of San Francisco, county of San Franclsco, State of California, have invented an Improvement in Head -Lights; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an adjustable headlight to be used on locomotives, vessels, and for other purposes; and it consists of a lantern mounted upon the front of the locomotive with a mechanism and means for operating the same, so thatit may be turned and concentrate the light at any desired point at either'side of the track or vertically up or down, as will be more fully explained by reference. to the accompanying drawings, in which" Figurelisaplan view showingaline of track and a train of cars with my adjustable headlight. Fig. 2 is a front elevation. Fig. 3 is a plan. Fig. 4. is a side elevation and a transverse section through the hollow shaft E and shaft K. Fig. 5 is a sectional elevation.

1n the usual construction and use of headlights for locomotives they are fixed to the front of the engine, so that the light is always thrown forward and concentrated in one line.

This shows the track clearly enough when the line is straight; but'if there are sharp curves the line of direction will throw the light out side of the line of the railswithin a few yards 1n some cases and leave the line of the track' or the inner line or embankment of the curve in comparative darkness. To overcome this difficulty and to provide an adjustment which will allow the engineer-to direct the light to various points off the line, the lantern A is supported upon a platform'or frame which may have a movement to right or left about a vertical axis, or up and down about a horizontal axis. This may be accomplished in various ways. In the present case I have shown avertical spindle or standard, B, which is journaled or supported so as to be capable of movement from side-to side about a vertical axis. A bevelfgear-wheel, O, is fixed to this In the present case I have shown the shafts E and G made hollow, the latter forming a hand-rail upon one side of the boiler, and it to the standard which supports the lantern,

and this is engaged by another gear wheel or pinion, J, which is fixed to the shaft K, turning within the hollow shaft E. Another shaft, L, extends through this hollow rail-shaft G, and terminates within reach of theengineer, with a hand-wheel, M, similar to the wheel H, each of them being operated independently of each other. The shaft 0 of the pinion I passes through the hub of the wheel 0 and has a gear-wheel, P, fixed to its inner end, which engages a curved rack, R, to produce the vertical movement, mounted in a curved. guide plate, I), of the standard or upright B.

A. bevel-gear, N, with one wheel upon the shaft L and the other, N, upon the shaft K, serves to transmit the niotion given the handwheel M to the lantern-frame and tilt it up or down about a horizontal axis. hen the Iantern is to be moved from side to side, both sets of gears must be moved together, which is done by grasping both parts of the divided wheel H; but when the wheel M is turned to move the vertical gear only the rear half of wheel H will be turned, the other half,with the horizontal gears, remaining stationary. By this arrangement the engineer is enabled to examine dangerous or doubtful parts of the road, and in stormy weather to turn the light upon threatening trees or masses of earth or rock upon either side which maybein danger of falling, so that if they appear in a dangerous condition he may instantly check his speed, or stop. the lantern so as to throw the light across sharp corners and examine the line of track at some distance ahead of the train and at points which would be entirely outof reach of the light in its usual fixed position.

It will be manifest that a lantern or head light having a similar adjusting mechanism This device also enables him to turn examined.

Having thus'deseribed my invention, what I claim as new, and desire to secn re by Letters Patent, is

1. The combination, with the lantern A, of the vertical supporting-standard provided with gear-wheel C horizontal shaft E, arranged at right angles to standard 13 andhaving mounted thereon gear-wheels D and D, and horizontal shaft G, arranged at right angles to shaft E and extending along parallel with and at one side of the boiler of an engine, and provided with gear-wheel F and hand wheel H, substantially as and for the purpose herein shown and described.

2. The combination, with the lantern A, of the curved rack R, shaft 0, having gear-wheel P and pinion I, shaft K, provided with gearwheels J N, and shaft L, provided with gearwheel N and hand-wheel M, substantially as and for the purpose herein shown and described.

3. The combination, with the lantern A, of the standard 13, provided with gear-wheel O, hollow shaft E, having gear-wheels D D, hollow shaft G, provided with gear-wheel F, curved rack R, shaft 0, having gear-wheel P and pinion I, shaft K, provided with gearwheels J N, shaft L, provided with gear-wheel N, and the divided handwheel H, substantially as herein shown and described.

In witness whereof I have hereunto set my hand.

WILLIAM DUTCH.
